Revered form guru and Betfair Informer Dominic Beirne is so impressed with Black Caviar, he believes she could win the Diamond Jubilee at Ascot at three-quarter pace.

Black Caviar will literally win this weekend's Diamond Jubilee Stakes at Royal Ascot in little more than a canter.

Well, at least, that's the conclusion of globally renowned form analyst and Betfair racing Informer Dominic Beirne, who has delved into his extensive database to provide Betfair with an exclusive ratings comparison on the eve of Black Caviar's debut overseas outing.

Dominic's assessment makes for unpleasant reading for British racing fans holding out hope of a surprise defeat by the Australian superstar.

"If I ranked the runner performance ratings for the starters in this year's Diamond Jubilee, Black Caviar would boast the top-16 ratings in the race," Beirne reveals.

"In other words, the worst of her top-16 ratings is superior to the best rating by any of her opponents.

Dominic believes Peter Moody's galloper can quite literally canter along and extend her unbeaten streak to 22 races.

"On past form, the highest any her opponents could be expected to rate would be 124, which is the potential rating of Moonlight Cloud, should that horse run to its peak.

"Black Caviar rates 124 going at three-quarter pace!

"Her career personal best of 136 was achieved in the Newmarket Handicap, where she carried seven pounds more than any other runner and ran 12-lengths faster than the par for open class races.

"This rating was two-lengths superior to the next highest in Australia for the past 20 years."

So, what do these numbers mean in terms of a likely outcome to the Diamond Jubilee?

"Black Caviar's PB of 136 is supported by a series of 131 ratings, therefore I would expect her to rate around 131 again and win by 3 lengths," Beirne predicts.

Betfair punters are shopping well, with Black Caviar trading @ Betfair odds of (1.23).

Ortensia's disappointing performance in the King's Stand Stakes on day one of Royal Ascot prompted layers to oppose the Aussie sprint form and offer Black Caviar at (1.37). Needless to say, the backers jumped out of trees to take those odds and she is back into a rock solid (1.23) and it would be no surprise to see that shorten even more.

Timeform's assessment of the Diamond Jubilee sums up what most racing fans suspect.

"The stage looks set for the outstanding mare Black Caviar to record an incredible victory number 22 on her first outing away from Australian soil."
